3.1 Overall Findings 3. RESULTS AND DISCUSSION Several general trends in the data presented in the following sections should be noted here along with several considerations of the use of marker compounds as "fingerprints" to trace aged AMOCO CADIZ oil in environmental samples. 3.1.1 Weathering of AMOCO CADIZ Oil The chemical composition of spilled oil from the tanker changed markedly over the first days to weeks, both at sea and once associated with sediment (Atlas et al., 1981; Calder and Boehm, 1981; Boehm et al., 1981). The changes are well documented in Figures 3.1 and 3.2 and are summarized in Table 3A. For comparison, the background saturated and aromatic hydrocarbon composition of sediment samples is illustrated. The non-impacted sediments contain: 1) an unresolved complex mixture (UCM) of hydrocarbon material in both fractions, 2) terrigenous nalkanes (odd chain) in the saturated fraction, and 3) pyrogenic PAH compounds in the aromatic fraction. Weathered AMOCO CADIZ oil is identified as such in the sections that follow based on the following: 1) The presence of large UCM in f^ and f 2 fractions with residual triterpenoid peaks. 2) The presence of isolated isoprenoid hydrocarbon compounds in the resolved (peak) part of the GC trace (in samples during the first year post-spill only) . 3) The dominance of alkylated phenanthrene (C 2 , C3, C4) , di- benzothiophene, naphthalene, and fluorene (in earlier compounds in the aromatic fraction and a dominance samples) of these aromatics versus pyrogenic PAH (i.e. fluoranthene, pyrene, benzanthracene, chrysene, benzopyrenes, etc.). 3.1.2 Persistence of Marker Compounds The most persistent compounds in the saturated (f^) fraction are the pentacyclic triterpanes (PCT) ; in the aromatic (f2) fraction the alkylated phenanthr enes (P) and dibenzothiophenes (DBT) are most persistent. To examine the PCT compound distribution, GC/MS analysis of the f^ fraction was necessary (e.g. Figs. 3.3 and 3.4). This results in a "terpanogram" yielding information on the relative concentration of eight PCT compounds used by several investigators as indicators of presence and origin of petroleum (e.g. Dastillung and Albrecht 1976; Pym et al., 1975) . Two PCT time series (Fig. 3.5) reveal that the PCT fingerprint is rather constant throughout the December 1978 to March 1980 time period 43
